11 Claims.

This invention relates to tabulating machines and, particularly, toimprovements in the mechanisms for listing, totaling and printing thedata which appears as perforations in cards or record -5 strips, andthis application is a continuation in part of my copending applicationS. N. 576,992, led Nov. 24, 1931.

Tabulating machinesy of necessity involve a variety of speciallyconstructed devices, because of the range of accounting problems forwhich they are used. However, the general structure of tabulators doesnot vary, no matter what may be the problem. Hence, the mechanism, whichis associated with some specic function of the tabulator, must bemodified according to the exigencies of the problem.- Generally, datafrom each card, which enters the sensing chamber, is listed, totaled andprinted. If there are as many as a hundred identical items in a group,the mechanism causes the printing of all of them, even though theinterest is centered on the total amount and not on the individualitems. A great saving would be effected if the items could beaccumulated and only the totals printed.

The principal object of this invention is to provide means forcontrolling printing mechanisms in a record controlled tabulatingmachine whereby common designation data contained in a group of recordsmay be printed on the same line of a report sheet with the totals of theassociated quantitative data.

General Description.

The present invention contemplates the combination of novel featureshereinafter to be fully described, and a printing tabulator of wellknown construction.

The tabulator, to which this invention is an improvement, may be dividedfor purposes of description into three sections. These sections will benamed in their order from bottom to top, the base, the intermediatesection and the head. They comprise mechanism for the purposes to behereinafter set forth, together with such bolts, screws, clips, pins,nuts, washers, and spacers as may be necessary for proper assembly.

The mechanisms of the base embrace the drive, the sensing, recordretaining, and change-ofdesignation mechanisms, the mechanism forconditioning the machine for total taking, and the necessary supportstherefor. Those of the intermediate section embrace mechanism fortranslating the data obtained from the card being sensed, and auxiliaryand supplementary mechanism which will be mentioned hereinafter. Thoseof the head embrace the alphabetic and computing units, the printingplaten, paper support and paper feed, and the mechanism associated withthe functioning of these several elements.

Framework-Figures 1, 2, 4 and 5 The mechanism of the several sectionsnamed above is housed in a suitable framework. The essential elements ofthis framework are: a base plate 28 (Fig. 1) supporting, at its outeredges, a pair of boxlike frames 2| and 22; cross bars 23 which tietogether the tops of the frames 2| and 22 (Fig. 2); open frames 24 oneof which is mounted upon each of the frames 2| and 22; a plate 25 hingedto the frames 24, which plate serves as a base for the mechanism of thehead, and a number of frames 21 (Figs. 4 and 5); which, with cross bars28 mounted thereon serve as supports.

Mechanism of the base-Figure 1 The base mechanism shown herein issubstantially the same as that disclosed in my Patent No. 2,044,119,issued June 16, 1936. Inasmuch as the several mechanisms that comprisethe base are well known in the art, and, further, do not form a part ofthe printing mechanism controls, they are described herein only insucient detail to enable an understanding of the present invention.

Journaled in the frame 2|, and extending from front to rear of themachine, is a main shaft (not shown) which drives the transverse shaft3|, feed rolls 32, skid rolls 33, and eject rolls 34 through suitablegearing. Suitable means for hand and power propulsion are provided inconjunction with the main shaft.

The shaft 3| lies horizontally and is transverse to the frames 2| and 22in each of which it is journaled. To the right end of shaft 3| is acrank which by means of suitable linkage actuates the mechanism of thehead section. The frame 22 houses cams 48, 4|, 42 and 43 (Fig. 3),mounted on shaft 3|, which cams control the card picker, the card stop,retract and total taking control mechanisms, respectively. Mechanismsfor clutching and de-clutching the main shaft to render the mechanismactive or inactive, and mechanism for actuating the card picker are alsocontained in frame 22. The frames 2| and 22 house gearing which drivesthe feed rolls. In addition, they serve as supports for the various feedroll shafts and the starting and stopping shaft.

Card picking-Figures 1 and 3 Mechanism is provided for picking the datacards singly from the bottom of a stack. The operation of this mechanismis as follows:

A stack of cards is placed in magazine 46 under a weight, which ensuresproper operatic-n of the picking edge of member 41. The spring 48attached at one end to arm 49, and at the other end to a suitableanchorage in frame 2|, maintains the follower 58 in contact with thepicker cam 48. The picker cam 48, turning with the shaft 3|, presentsits low dwell to the follower 58 once during each cycle of the machine.When this occurs, arm 5|, link 52, arm 49, shaft 54, arm 55, link 56,and picker 41 are moved rearwardly by the action of spring 48 (to theright as seen in Fig. 1), and one card is fed past throat knife 45 intoengagement with the feed rolls 32, which pass it onward toward thesensing chamber 15. rlhe high dwell on cam 48 restores picker 41 to itsinitial position.

Mechanism is provided whereby the picker 41 may be locked againstoperation. This mechanisrn consists of a latch 51 in cooperation with anotch 58, located in the top edge of the link 52. When totals are taken,the feeding of cards must be suspended, until the totaling operation iscomplete. The mechanism, which controls the latch 51, will be describedunder Automatic total mechanism.

Sensing mechanism-Figures 1 and, 3

Mechanism such as is shown in the above cited Patent No. 2,044,119, andillustrated in Figs. l and 3 hereof, is provided for sensing the datawhich is perforated in the cards. This mechanism may be divided intothree groups, namely, card stop, card sensing, and pin latching.

The operation of the card stop mechanism is as follows; when roller 6|,which is mounted on arm 82, reaches the high dwell on cam 4|, whichturns with shaft 3|, link B3 moves downwardly causing arm 64, which ismounted on shaft 65, to be oscillated. This oscillatory motion iscommunicated to arm 66 through shaft 65, and

` causes link 61 to be moved upwardly, thereby rocking lever 68 andforcing support 69 and stop 18 downwardly against the tension of spring1|, blocking the exit of the sensing chamber 15.

The operation of the sensing mechanism is as follows:

Eccentrics 16 mounted upon shaft 3|, cause eccentric straps 11 to riseeach time the shaft 3| turns and thereby elevate the sensing box 18,which is pinned to said eccentric straps. The pins 19 are sustained bytheir respective springs and hence rise with the sensing box. Those pins19 which nd perforations in the card in the sensing chamber retain thefixed relation to the sensing box and pass through the perforation.Those pins, which do not find perforations, are held down against theirrespective springs, whereupon those pins which are elevated are lockedby slides 88.

The operation of the mechanism which locks the sensing pins 19 duringsensing is as follows:

Immediately after the rising sensing pins 19 pass into the perforationsin the sensing chamber, the rising sensing box 18 removes roller 8| fromcontact with the fixed cam 82. lThe spring 83 causes the lever 84 torock counterclockwise as viewed in Fig. 1. Links 85, one for eachlocking slide, are supported between rod 86 and rod 81. 'I'hecounterclockwise rocking of lever 84 will, therefore, cause the notchesat the top of the slots in locking slides 88 to engage the extrusions onthose sensing pins 19 that are in elevated position. Upon the descent ofthe sensing box 18, the roller 8| again contacts the stationary cam 82and the locking slides 88 are retracted and the sensing pins 19 arereleased.

Card ey'ecting-Fzgure 1 When card stop 18 is elevated, which occurs justafter the receding sensing pins are clear of the sensing chamber, thecard moves onward under action of skid rolls 33 (Fig. l), until it isengaged by eject rolls 34, which carry it onward into receptacle 88.

Record retaining-Figures 1 and 3 Supported on the cross-bars 23 is therecord retaining mechanism |88 of the form disclosed in above citedPatent No. 2,044,119.

The record retaining mechanism operates as follows: Each of the recordretaining pins |8| is arranged in exact vertical alignment with itscorresponding sensing chamber perforation and sensing pin 18. A lockingslide |82, urged to locking position by spring |83, is associated withthose pins |8| which correspond to a single column of a card. Thegeneral structural features of slides |82 are the same as those ofslides l agi-nasse 4"81). Eachpinxlihasa flattened portion, whichcarries.c twof extrusions, one for locking the pins .and the` other forusein connection with the @change-of-designation mechanism. As' a recordretaining pin llliis elevated by' the" actionfof a sensing pin '19, thelocking extrusion Wipes the "cam `shaped side of the 'associatedslot inslide |02`, against the actionI of a spring ||.'|3,until the l extrusionsnaps into thenotch at thetop of its slot and is locked in upperposition thereby. When retaining pins `lill rise in response tothesensing of the next succeeding card, the ex- 4which are iixedlymounted on shaft E66.

.trusions on. these pins cam the locking slide as Vdescribed above, andin so doing release the prel'viousse'tting of the recordretaining pins.AHowever, in order to decrease the time of operation of the recordretaining unit and for other purposes to be considered later on a bailHill is pron vided. Thisbailis supported between arms |65 An arm ,|01FigS) also fixed' on shaft |536 is maintained in. cooperable relationwith link |08 ,by the united actionv of springs H33. The link is ypivotally mountedfat its lower end to an arm lIJS' which is journalledon a stud in frame 22.

and which cooperates with cam 42 jthrough a `follower journalled on theside of the arm. 'I v l behang@ of designation-Figures 1 and 3 `30Mechanism is provided whereby totals maybe taken,r when there is achange in the subject matter indicated by perforations inA any pre- 'iselected kcolumn ,of the card. Such a change is fof its slots.

generally called a Change of designation, and fthemechanism associatedwith the operation is v called change ofdesignation mechanism.

Ther operation of vthe change 'mechanism is as follows:

`The manipulative interponent H0, associated of designation with thecolumn in which the designatory matter appeara'is lowered until itsbottom end stands between the bail Ill, which is supported'by arm 'I |12fixed on shaft! lil, and the end of a slide I4. disclosed in Patent No.2,044,119, the slide l I4 has a cam surface along one of the' sides ofeach Since, any pin mi, which is elevated by reason of sensing of aperforation in a card, will remain elevated by the action of a cor- Yresponding locking slide |52, the pins remain ele- `vate'd 'as long asthe perforation inthe pre-se- `looted column remains unchanged as tolocation. When-the position of the perforation changes, Y the ilppfrextrusion on pin ii cams the slide |.I4`y forwardly, releasingthepreviously elevated pin il!! and forcing the lassociated linterponent vlI6 andybail` I il forwardly, thereby tripping the automatic totalingmechanism, as will now be describedv 60 y Total taking controlmechmlism-Fz'gures `1 and' 3 A totaling cycle maybe initiated byspecialconditions such as special total cards (a special perforation inthev 12th position or 45th column),

change of designation (a shifting of any one or more. of a set ofpre-selected slides H4) rocking of shaft. H3 manually, etc. Whatever theorigin of a card in the sensing chamber. `should not-have its itemsadded into the totalizers ofthe initiation of a totalingoperation, it isini-v tiated by rocking shaft H3. The conditions differing from a normalaccumulating cycle are controlled by a set of cams on the intermittentlyopatthisctime ynor should itbe ejected,.therefore,. it

-rnusti` be held in the sensing chamber, the stop setting function ofthesensing pinsk 19 must be disabled,.or what amounts tothe same thing theactuator stops must be retracted before the actuators start forward, andthe picker must be disabled to prevent the feeding of another card intothe sensing chamber.

To accomplish this, mechanism, such a's that described in above citedPatent No. 2,044,119, is provided Vto prevent card feeding, to hold thecard stopiii in active position, and to hold the sensing pins 19retracted until the total operation is completed. d n

The operation of the automatic'totaling mechanism islas follows:

During tabulator cycles latch H6 (Fig. 3) supported by bracket l'l (Fig.2), engages detent arm Mii and arm H9 (see Fig. 3) and holds pawl i253from being actuated by cam 43. When a total taking operation isinitiated, shaft H3 is rocked. thereby rocking tripping latch HS vfixedto said shaft `i i3. This motion of the tripping latch H6 releases arml!!! and permits it to rock counterclockwise to position pawl l2@ foractuating ratchet |2i.r Cam 43 on shaft 3| then rotates to raise rod 22,arm H9 and pawl |29, causing Y ratchet i2@ to turn the shaft H5 onetooth'space setting 'of those pins ll, which correspond to perforationsin the card then in the sensing chamber. The next rotation of cam 43advances theshaft liionemore notch, as measured on the detent and thetotal cam |40 turns to actuate the totaling mechanism as will be shownunder Control of total shafts.

Cam |59 which .is mounted also on shaft H5,

in the meantime acted upon follower |5l,

thereby causing arm |52 to be oscillated about its fulcrum to force link|53 downwardly and rock arm |54 and shaft |55, which sets latch 5'! toengage the notch 58 in the link 52 of the picker mechanism.

Mechanism of intermediate section-Fz'aures 1 and 2 Frames 2d providespace for the translator unit ist (sometimes called connection box).

,These frames also support shafts, links and levers incidental to thecontrolof a portion of the mech.-`

anism of the head, allof which functions will be taken up underappropriate headings.

Translators-Figures 1 and 2 The translator units, which may be selectedfor use in connection with the mechanism of the present invention,follow the principles of design and construction previously disclosed inmany patents to Powers and to Lasker.

' In Fig. 1 of this application, there is shown conventionally a typicalarrangement of translator unit wiring. It is well known that the wiringarrangement may be varied to suit the solution of 'a particular problem.In a translator unit there are a number of wires iti equivalent to thenumber of. record retaining pins mi. Whenever a recordv retaining piniselevated by a sensing pin 19', thecorresponding wire |6| is alsoelevated.

Head section-Figures 1, 4, 5 and 6 Mechanisms are provided in the headfor accumulating and printing the totals of numeric values, for printingword descriptions of the printed entries, and for controlling theoperation of the rst two named mechanisms. Computing units is the termusually applied to the groups of mechanisms associated with thetotaling. Alphabetic units is usually accepted as a correct term for thegroups associated with printing word descriptions.

The mechanism of a computing unit comprises a stop basket, the stopelements of which are arranged in columns, with type carriers,actuators, accumulators, and printing hammer mechanisms equal to thenumber of columns of stop elements. Computing units will be providedwith both front and rear accumulator, when grand totals are to be taken;otherwise only front accumulators will bepresent. An alphabetic unitcomprises a stop basket, the design of which is, in general, similar tothat of a computing unit, type carriers and printing hammer mechanisms,there being one of each for each column of stop elements.

The mechanism, which is Classifiable as controlling means comprises;total shafts, non-add shaft and its controlling mechanism; mechanismsfor setting accumulators for totaling operations, for releasing Zerostops, for setting slam checks, for disabling conflicting totalizers,for releasing non-add mechanism, for setting sub-total slides, lorcontrolling non-add shaft, for changing the timing of totalizers and forspecial control of printing hammers. There are provided, also. means forsuporting and feeding paper' and mechanism for controlling line spacing.These various mechanisms will be described hereinafter.

Stop baskets-Figures 1 and, 7

Mechanism is provided for stopping the type carriers at a point whichwill give a printed record of the perforations as they are translated bythe translator unit. This mechanism is frequently called a stop basket,a typical form being shown in Fig. 1, and another (alphabetic) in Fig.7.

The form of stop basket adapted for use herein is that disclosed inpatent to Lasker No. 1,780,621, dated November 4, 1930, and is generallycalled a ninety-column basket. Interpretation of ninety (90) columntwo-hole code makes use of the combination of each odd digit and nine(9) to produce the next higher even digit. Each elevated wire 16| sets astop |65 in position to intercept its associated actuator sector |66 andtype carrier |61 to produce a record, which is in accordance with theinterpretation given by the wire. The elevation of any stop |65 causesan extrusion thereon to cam against its associated tooth on slide |68,forcing said slide rearwardly. 'Ihe cam face at the rear end of slide|68 acts upon an extrusion on zero stop |69, drawing it downwardly andreleasing actuator |66. The elevation of block |10 by the wire |61 whichis associated with digit nine causes the release of actuator |66 asabove described, cross bar 11| serving as the stop for the nine (9)position.

When any stop is elevated, in conjunction with block |18 to set an evendigit, the toe at the top of block |16 is moved out of contact with itscheck plate |12, and is, therefore, free to be set forward by the actionof actuator |66 in contact with the raised stop |65. VThe amount of theforward set is suflcient to bring the actuator to a positioncorresponding to the even digit next above the associated odd digit.When zero is to be printed, there is no actuation of mechanism since allactuators |66 are initially at Zero position.

Actuators and type carriers-Figures 1, 6 and 7 Mechanism is provided innumeric units for setting type in a position for printing theinterpretation of the perforation in the card. This mechanism isdisclosed in patent to Powers No. 1,245,502, dated November 6, 1917, andis shown in Figs. 1 and 6 hereof.

Actuator sector |66 and type carrier sector |61 are journaled on shaft|14 and are constrained to maintain a fixed relation to each other byspring |15 and pin |16. Spring |11, which is normally kept undertension, by means to be hereinafter described, is attached at its upperend to the rearwardly extending arm of type carrier |61 and at its lowerend to a suitable spring anchor.

Means for actuating accumulator wheels is provided by cutting gear teethon the forwardly extending portion of actuator sector |66. Hence, sector|66 acquires the generally accepted title of actuator.

The operation of the actuators and type carriers is as follows: Bail|18, the construction and operation of which will be describedhereinafter, swings forwardly after stops |65 are set. Springs |11 causetype carriers |61 and actuators |66 to follow bail |18 until a set stopintercepts the heel on actuator |86.

Modication of the type setting means of the numeric units is necessaryin alphabetic units (see Fig. 1). These modifications apply particularly to members |66 and |61. the numeric unit is replaced by stopsector |80, and type carrier |61 is replaced by type carrier I8|. Thismechanism has been previously dislgogsd in my Patent No. 1,768,526,issued June 24,

causing type carrier |8| to be extended under f combined action ofsprings |81 and |88. As in the numeric sector, the contact of the heelon the stop sector |88 with a stop pin |82 in the stop basket positionsthe type carrier 8| for printing.

Type carrier control- Figures 1 and 7 Mechanism is provided in eachcomputing unit to control the advance and return of the type carriers.This mechanism has been disclosed in many of the applicants priorpatents, including Patent No. 1,780,621, dated Nov. 4, 1930, and isillustrated in Figs. 1 and 7 of the present application.

The operation of this mechanism is as follows:

Fan cam |90 (Fig. 1), moving forwardly under control of oscillatingshaft ISI, pulls link |92 and oscillates cam |93, clockwise about shaft|94. Follower |95, mounted on arm |96, is constrained to follow the pathof cam |93 and in so doing rocks arms |96 and bail |18 clockwise aboutshaft Actuator |66 of nl', thus'permittin'gtyp'e carriers |61 ftoadvance. .The return of fan-cam |90 will obviously reverse the directionof motion vof the above described members and return type sectors |151to their initial position.

' *Mechanismg which is a modicationlof thatjust described, is provided fin leachalphabetic printing ,unitvfor the 4control ofV the 'advance andVreturn of its type carriers. This-mechanism `is fullydisclosed in `thelcited patent to Lasker No, 1,768,526,

' and is shown herein in Fig. 7.

mechanism is .as follows:

called they front totalizers and the rear totalizers.

The mechanism of a 'front totalizer 2|!) is shown in Figs. V1 and 8 andis substantially the `same as that disclosed in the patent to PowerslyNo. 1,245,502.' f ,f

The operation of 'the 'fro-nt accumulating `Let it .be assumed thataccumulator wheels 2| are in mesh with actuators |66. lilzachyaccumulator wheel 2|| has' ten teeth, the spacing of ,which is the sameas that of the type on carriers |61 and cn actuators |66.v Hence, eachac- 1 "tuator |66 is suited to turn its associated wheel 2|^`| mountedon shaft V2|2 through a number Yof teethy corresponding Vto the digit4which vhas been i y set.

The rruchanism of the rear totalizer 2|5 is y ysubstantially the same asthat disclosed in my `lcopending application S. 5N. 681,333, filedDecember 18,1923, and is shown in Figs. 1,'4, 5 and 13. It consists ofpin 2|6, link '2|'|, actuator rack 2|8, pin 219, accumulator wheels 220,'shaft 22,1, Camming plates222 and Ashaft 223.

222|, rwhich is carried by 'camming 'plates 222 -flxed1y mounted on'Shaft 223.

' The operationof the rear totalizer 2|5 is as :it be" assumed thataccumulator wheels 220 are in mesh with 'actuator racks 2|8. Eachaccumulatoriwheel 220 has ten teeth and, when an vactuator rack Y2|3 isadvanced under the influence of 4any actuator sector 166, the associatedaccumulator "wheel 22|) will advance a number of teeth corresponding tothe setting -of the stop |65 in the associated -column -in the stopbasket.

Transfer mechanism-Figures 1, 4, 5 and 13 v lVIechanism, commonlyreferred to as "trans fer `mechanism, is provided. In tabulators, whichare equipped with 'front and rear totalizers, it is obvious that twosets of 'transfer mechanism are necessary.

The transfer mechanism for front 'totalizers is disclosed vin the patent'to Powers No. 1,245,502, dated November 6, 1917, and is shown in Fig.'1 of the present application. It consists o'f a trip-v ping toothintegral with the tenth tooth of 'each accumulator' wheel 21| and stoparm 225.

The operation of 'this mechanism is well 'known and need not bedescribed further.

The transfer mechanism of the rear totalizer is disclosed in my citedcopending application N. 681,333, vand is shown in Figs. 1, 4, 5 and 1'3of the present application. Itconsists of 'tripping tooth 22?, arm 228,spring '229, latch 230, bar 23|, 15111232, and adjustable bar 2'33.

The rearward travel of fan cam l|90will reverse the motion 'ofmembers 243 and l'245 and draw accumulatoreinto engagement with actuators v|66 at approximately the 'time `whenthey are ready to returnaftera printing operation.

The mechanism for timing the rear totalizer, which is substantially thesame-as that disclosed in my cited 4copendingapplication S. N. 681,333,is'shown in Figs. 5, 6, and l0 hereof fand consists of shaft |9I, fancam 250, wiper1'25-l, spring252, shaft 253,v rocker 254, pins255 and256, link25-1,

crank 258, shaft V'223 Vand camming `plates 222.

Fan cam 25D is fixed to shaft 19|. Wiper 25|., shaft 253 and rockerA251-are:assembled -in'rthe same vmanner as is the like mechanismassociated with the front totalizers. VThe forward end of link`25`|isurged upwardly bya spring 460, extended between :the frameoftheimachine and a stud 46| that extends beneath the lower edge of link251 and is mounted on a latch 462 which, in turn, is pivotally mountedon link 251 at'463. In -this manner, a notch 258, cut in the upper edgeof link 251, is-normally urged into engagement with the upper pin 255 onrocker 254. The arrangement of latch 462 is such that, in the normalposition of the parts as shown in Fig. 5, the lower edge thereof issubstantially parallel to and lower than the lower edge of link 251 andthe forward edge thereof overlies and extends beyond pin 256 on rocker254. The rearward end of link 251 is attached by a spring and pin inslot connection to a crank 258, fast on shaft 223. Also fast on shaft223 are the cammingplates 222 which support the shaft 22| on which therear accumulator wheels 226 are mounted.

During accumulating cycles, the operation of the rear totalizer timingmechanism is identical in principle to the corresponding mechanism ofthe front totalizers, i. e., at the beginning of each cycle, the forwardmovement of fan cam 250, by means of wiper 25| and pin 255 on rocker254, serves to shift'link 251 rearwardly to rock shaft 223counter-clockwise and thereby cam wheels 220 out of engagement withracks 2l8 prior to the forward movement of the racks; whereas, slightlyafter the midpoint of each cycle, the rearward movement of fan cam 250shifts link 251 forwardly and thereby causes the engagement of thetotalizer prior to the rearward movement of the racks so that the amountregistered by the racks is rolled into the rear wheels.

Control of total shafts-Figures 1, 3, 5, 6', 8 and 10 Mechanism isprovided for controlling the timing of the totalizers to extract thetotals. This mechanism includes the total shafts and their associatedmechanism. Since there are two sets of totalizers, two sets of timingcontrol mechanisms are necessary. In the present instance, the fronttotalizers are used for group totals and the rear totalizers are usedfor grand totals. Hereinafter, these mechanisms will be referred to astotal and grand total mechanisms, and the front totalizer will be calledthe totalizer, while the rear totalizer will be called the grandtotalizer.

The mechanism for the timing control of the total and grand total shaftsis shown in Figs. 1, 3, 5, 6, 8 and 10, and consists of cam |40, foil-ylower 260, lever 26|, spring 262, arm 263, T- headed link 264, lug 266,spring 261, shaft 268, link 269, arm 210, total shaft 21|, arm 212, lug213, link 214, arm 215, and grand total shaft 216. Cam |40 is mounted onshaft ||5 of the automatic totaling mechanism and follower 260 and lever26| are kept in contact therewith by spring 262 associated'with arm 263.T-headed link 264 is pinned at its lower end to the forwardly extendingarm of lever 26|, while its T-shaped upper end 265 is supported by a lug266 on the side of arm 263, being kept in contact therewith by spring261. Pivoted to arm 263 which is journaled on shaft 268, is link 269,the upper end of which is pivoted to arm 210 xedly attached to totalshaft 21|. Journaled on shaft 268 and lying parallel to arm 263 (beyondit in Fig. l) is grand total arm 212, on the forward end of which is lug213 and upon which is pivoted link 214. The upper end of link 214 ispivoted to arm 215 which is fixed to grand total shaft 216.

The operation of the mechanism for actuating total shaft 21| is asfollows:

When cam |40 turns, during Athe operation of the total taking controlmechanism, lever 26| is turned counter clockwise, pulling link 264dowinwardly and rocking arm 263 by means of a lug 266 on the side of thesaid arm. Also, this motion causes link 269 to be drawn downwardly,thereby rocking total shaft 21|.

Mechanism, which is associated with that above described, is providedfor actuating the grand total shaft 216. This mechanism consists of Wire280, arm 28|, shaft 282, arm 283, link 284, screw 285, pin 286, arm 281and spring 261. Wire 280 is pivoted on the rearward end of arm 28|,which is xed to shaft 282. Arm 283 alsois fixed to shaft 282 and extendsupwardly to contact the rearwardly extending forked end of link 284,which is pivotally attached to T-headed link 264 by screw 285 and isheld in correct position by a pin 286 in the downwardly extending arm281 of link 284 and spring 261. Shaft 282 and arms 28| and 283 aremounted on the front frame of the translator |60.

The operation of this mechanism for actuating grand total shaft 216 isas follows:

When a grand total perforation is sensed by pin 19, wire 286 iselevated, rocking arm 28|, shaft 282 and arm 283 counter clockwise, asviewed in Fig. l. Link 284 is forced forwardly, against the restraininginfluence of spring 261, thereby rocking link 264 until head 265 liesabove the lug 213 on the side of arm 212. Turning of cam |48 thus causeslink 264 to pull link 214 downwardly and rock grand total shaft 216.

Control mechanisms Mechanism under control of total shafts 21| isprovided for:

1. Changing the time of the totalizers.

2. Depressing the zero stop of the units in which totals are to betaken.

3. Setting the slam preventing mechanism.

4. Unlocking the printing hammers associated with the unit in whichtotals are taken.

5. Feeding the paper to the correct line.

6. Releasing the non-adding mechanism.

The operations above listed occur during the taking of a total andresetting of the machine.

Change of totaliaer timing-Figures 1, 5, 6, and 10 Mechanisms areprovided for changing the timing of both the totalizers 2|0 and thegrand totalizers 2|5.

The mechanism for changing the timing of the totalizers 2|0 is similarto that shown in the cited Powers Patent No. 1,245,502, and in Figs. 1,5, 6, and 10, herein.

The operation of this mechanism is as follows:

When total shaft 21| is rocked during a total taking operation, itforces pin 29| which extends laterally from the side of arm 292 to movebell crank 293 clockwise as viewed in Fig. 1. Link 294 is lowered andthe lower notch in link 243 engages the lower pin 246 on rocker 242.Hence, when fan cam |80` moves forwardly, rocker shaft 24| and rocker242 are turned clockwise, link 243 and camming arms 245 are pulledforwardly, and accumulator wheels 2| are brought into con,- tact withactuators |66 at a time when said actuators are in condition for beingadvanced. Hence, the amounts standing on said accumulator wheels 2||will be set up in printing position on type carriers |61 for a totalprinting.

For taking grand totals, means are provided to control the timingmechanism of the rear totalizer to cause the engagement of wheels 220 vtheV racks, and the disengagement ofthe wheels prior ,to ,`the"return ofthe racks'.

'D ring .this k, clockwise movement of rocker 25d;

that the-zero stops are retracted whenshaft 3|0 is rocked clockwise(Fig. 4, counter-clockwise in Eig. 1).

The construction is such that during the latter part of each machinecycle, the last portion of the counter-clockwise movement of shaft |9|urges arm 35 against pin 306 (as in Fig. ll) to move slide 301 and link308 rearwardly, thereby rocking shaft 3|0 clockwise to retract zerostops |69. By this arrangement the zero stops are depressed during theperiod in which the digit stops are elevated (see also Fig. 15),- thedigit stops serving merely to c-am slides |68 (Fig. l) rearwardly.` Inthe. meantime, the type carriers |51 are held in their rearmostpositonby the associated restoring hails` l'l.

`As shaft lill` begins its clockwise movement during the next. cycle,arm Still is withdrawn from pin 366 and the spring on link 368 restoresshaft 3|() to its former positon, to release zero stops |69, prior tothe forward movement of the type Thus, in the columns in .which no digitstop yhas `beenraised, the Zero stop |69 is elevated by its spring tohold the associated type carrier in its rearward position; wher-eas, inthe columns in which a digit,V stop has been raised, the cam slidel',which is held rearwardly by the elevated digit stop, retains the zerostop 4inl its lower positionthere`by permitting the advance of the typecarrier.
